Hydrant



UNiTnn STATES PETER- WHITE, OF ST. LOUIS, MISSOURI.

HYDRANT.

SPECIFICATION forming part of Letters Patent No. 270,354, dated January 9, 1883.

Application tiled April 22, 1882. (No model.)

To all whom it may concern:

Be it known that I, PETER VHITF., of St. Louis, Missouri, have made a new and useful Improvement in Hydrants, ot' which the following is a i'ull, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a vertical section of the improved h t drant; Itig.2,ave.rtical section taken on the line 2 Zot' Fig/4; Fign, a section similar to that ot Fig. 2, but showing the valve lifted; Fig. 4, a horizontal section taken on the line 4 l of Fig. 2; and Fig. 5, a horizontal section taken on the line 5 5 of Fig. 3.

'Ihe same letters denote the same parts.

The present improvement relates to the means for controlling the waste from the hydrant, to the inode ot' connecting the housing, valve-chamber, and valvei`oot,a nd tothe means for enabling` the valve to be lifted properly out of the valve chamber.

A represen ts what may be termed the valvefoot. It supports the valve and parts immediately therewith connected and the housing ot' the hydrant, the valve-chamber B being seated at a in the i'oot, and the housing O being screwed at c into the loot. A packing, l), is interposed between the valve-chamber and the seat. a, and the valve-chamber is provided with a iiange, b, upon which the lower end of' the housing bears when the latter is screwed down into the foot. This serves to i'asten the valve-chamber in the valve-foot.

E represents the valve. It seats at e. It is attached to the hollow. stem F, a metallic washer, G, being just above the valve.

H represents the cap ofthe valve-chamber. A cup-leather, I, is interposed between the cap and the top ofthe wall bof the chamber. It serves to pack the cap, but more particularly for closing the waste-passagef when the valve is lit'ted, and as follows: In the side ot' the stem F is a passage, f, through which the water is wasted trom the valve-chamber into the space J between the housing and the valvechamberthat is, when the valve is seated, as in Fig. 2, the water passes from the interior of the stem F and the chamber B into the passage f, thence into the space J, and thence. out through the opening c in the housing; but when the valve is lifted, as in Fig. 3, the passage f comes opposite the cup-leather, and is is again seated.

The usual discharge-pipe, K, is screwed into the upper end ofthe stem F. The latter is provided with an arm, j", which, when the stem is turned to unscrew it. comes against an arm, h, upon the cap H. This enables the operator to unscrew the cap from the valvechamber and to lit't the valvestein, valve, and cap from the valve-chamber and out ofthe housing. Now, the washer G is larger in diameter than the stem F and the opening in the cap H, and, incase the cap is not entirelyr detached from the valve-chamber, the washer prevents the valve from being withdrawn from the valve-chamber, and thus the operator is enabled to determine whether the cap is detached from the chamber. The water enters through the foot A, and is discharged (past the valve E) through the stem Fand pipe K, in the usual manner.

The extension B of the chamber B serves partly to Center the chamber in the foot, but more especially to hinder the water from passing `from the interior ot' the foot to thejoint between the chamber and the foot.

I claiml. In a hydrant,the combination of the housing O, the cap H, the valve-chamber B, the

passage f, substantially as described.

2. The combination ofthe valve-chamber B, the cap H, the leather I, the stem F, having the waste-passage f, and the housing O, having the passage c, substantially as described.

The combination, in a hydrant, ot' the foot A, the chamber B, having the tlange b, and the housing O, substantially as described.

4.. The combination ot' the chamber B, the cap H, the stem F, the valve E, land the washer G, as and forthe purpose described.

5. The combination, in a hydrant, of the foot A, the chamber B, having the liange b, the packing D, and the housing O, substantially as described.

6. The combination, in a hydrant, ot' the valve-chamber B, having the extension B", and the toot A, substantially as described.
